A Syrian man walks by a building destroyed in an airstrike in Aleppo city, Syria, Friday, Aug. 17, 2012. Rebel footholds in Aleppo have been the target of weeks of Syrian shelling and air attacks as part of wider offensives by President Bashar Assad's regime. Rebels have been driven from some areas, but the report of clashes near the airport suggests the battles could be shifting to new fronts. (AP Photo/Khalil Hamra) less
